Hello everyone!
I bought a GLinet router to be able to use it as a “vlan” or “NAT”, where devices connecting to the GLiNet can only communicate with each other by their local GLiNet IPs and isolate the local router IPs from the ISP.
But it is not working that way, for example:
A laptop connected to the GLiNet router that is assigned the local IP 192.168.8.10 can still access the local IP of a PC connected to the Internet provider’s router (192.168.1.20).
How can I prevent any device connected to the GLiNet router from being able to access devices connected to the ISP’s router, without losing Internet on the GLiNet router?
Or can’t this configuration be done? Thanks for your help.
A company has this need. It wants to give remote access to several devices to some employees but they do not want it to access the devices connected to the ISP’s router, because they have a local server on that router that is only used by management.
Let’s say that this local server is located on the local IP 192.168.1.123 the employee connected to the device on the GLiNet router that has the local IP 192.168.8.5 could access the local server (192.168.1.123) and this could not happen because it would access the data on the local server.
Therefore, all local ports on the ISP’s router needed to be blocked for employees using devices on the GLiNet router.
In the end it was achieved with @EddieA solution, in this case the GLiNet router is running as a vlan.
